A mobile application for execution upon an electronic device for an amusement park or waterpark. The mobile application provides information, entertainment or other convenience data to the user while the user is within the park. The mobile application may be configured to determine a position of the electronic device within the park and display notifications including discounts at nearby vendors or restaurants, menus of nearby eateries, or ride recommendations based upon wait times. The mobile application may allow the user to make reservations at nearby restaurants within the park. The mobile application may generate an efficient ride sequence for the user based upon characteristics of either the user or the user's participation within the park and navigate the user around the park according to the ride sequence. Puzzles, games, or other entertainment or educational activities may be displayed to the user for providing rewards based upon their participation.

A vacuum sewage system includes a collection station, a variable speed vacuum pump, a variable speed drive, a control system, a sewage pump, a collection tank, a valve pit, a first conduit extending from the collection station to the valve pit, a second conduit extending from the valve pit and terminating in a closed end, a sensor located adjacent the closed end of the second conduit, and a valve located in the valve pit for selectively permitting sewage and waste water to flow from the valve pit toward the collection station upon activation of the valve. The control system, variable speed drive and sensor may be utilized to adjust the vacuum level and vacuum level range at the collection station so as to reduce the speed and operation time of the variable speed vacuum pump while maintaining the desired vacuum level in the vacuum sewage system.

Hemodialysis and similar dialysis systems including a variety of systems and methods that make hemodialysis more efficient, easier, and/or more affordable, and include new fluid circuits for fluid flow in hemodialysis systems and a reciprocating diaphragm pump for pumping fluids. The reciprocating diaphragm pump includes a flexible diaphragm, a first rigid body having a curved pumping chamber wall, a second rigid body having an opposing curved control chamber wall. The diaphragm is interposed between the pumping chamber wall and the control chamber wall to define a pumping chamber and a control chamber. The diaphragm of the pump has a peripheral bead arranged to locate the diaphragm between the first rigid body and the second rigid body and a diaphragm body having a curved, semi-spheroid or domed shape. The diaphragm is pre-formed or molded so that during a delivery stroke of the pump, the elastic force of the diaphragm resisting its deployment into the pumping chamber prevents a peripheral portion of the diaphragm body from fully contacting the pumping chamber wall.

This disclosure relates to a method for temporarily interrupting an extracorporeal treatment of blood of a patient by use of a blood treatment apparatus. The method comprises activating or controlling a control device provided and configured to bring the blood treatment apparatus into a state in which the blood treatment of the patient can be interrupted with the intention to continue the blood treatment. This disclosure further relates to a control device, a blood treatment apparatus, a digital storage means, a computer program product as well as a computer program.

A pumping cassette including a housing having at least two inlet fluid lines and at least two outlet fluid lines. At least one balancing pod within the housing and in fluid connection with the fluid paths. The balancing pod balances the flow of a first fluid and the flow of a second fluid such that the volume of the first fluid equals the volume of the second fluid. The balancing pod also includes a membrane that forms two balancing chambers. Also included in the cassette is at least two reciprocating pressure displacement membrane pumps. The pumps are within the housing and they pump the fluid from a fluid inlet to a fluid outlet line and pump the second fluid from a fluid inlet to a fluid outlet.

A gas turbine engine includes a fan shaft diving a fan having fan blades. The gas turbine engine also includes a gear system including a sun gear surrounded by a plurality of intermediate gear, a carrier at least partially supporting said plurality of intermediate gears, and a ring gear surrounding said plurality of intermediate gears, wherein said sun gear is driven by a turbine. The gas turbine engine also includes a flexible coupling fixing said ring gear from rotation relative to an engine static structure and a lubricating system for said gear system. Said lubricating system includes a lubricant input, there being a stationary first bearing receiving lubricant from said lubricant input. Said bearing has an inner first race in which lubricant flows, and a second bearing for rotation within said first bearing. Said second bearing has a first opening in registration with said inner first race such that lubricant may flow from said inner first race through said first opening into a first conduit. Said first conduit is in fluid communication with said plurality of intermediate gears. A gas turbine engine is also disclosed.

A system for tracking guests and collecting feedback for an entertainment attraction. The system may determine a guest's position and may interact with the guest via user interface provided for example via application on mobile device or kiosk, in order to assess guest satisfaction before, during and after attendance at an entertainment attraction or amusement park. The system may allow for storing the guest feedback and may determine whether to issue a reward to the guest based upon the feedback provided. The system may be positioned proximate to a queue line for an entertainment attraction, and may capture an image of a guest to determine the perceived mood of the guest and thereby determine whether to issue a reward to the guest based upon the perceived mood of the guest. Guest interfaces may allow communication or other data presented between or to guests.

Systems and methods for analysis of samples, and in certain embodiments, microfluidic sample analyzers configured to receive a cassette containing a sample therein to perform an analysis of the sample are described. The microfluidic sample analyzers may be used to control fluid flow, mixing, and sample analysis in a variety of microfluidic systems such as microfluidic point-of-care diagnostic platforms. Advantageously, the microfluidic sample analyzers may be, in some embodiments, inexpensive, reduced in size compared to conventional bench top systems, and simple to use. Cassettes that can operate with the sample analyzers are also described.

The disclosed embodiments include a method, apparatus, and computer program product for improving the accuracy of a rate of decay measurement for real time correction in a mass flow controller or mass flow meter by using a thermal model to minimize thermally induced error in the rate of decay measurement.

The present invention relates to a method for temporarily interrupting an extracorporeal treatment of blood of a patient by use of a blood treatment apparatus. The method comprises activating or controlling a control device provided and configured to bring the blood treatment apparatus into a state in which the blood treatment session of the patient can be interrupted with the intention to continue the blood treatment session. The present invention further relates to a control device, a blood treatment apparatus, a digital storage means, a computer program product as well as a computer program.
